Abstract
The present invention relates to a kind of satellite communication system disturbance restraining method and communication system, satellite communication system mainly includes ground communication station and telecommunication satellite, relay station is used satellite as to forward radio wave, so as to realize the communication between two or more ground communication stations.Because antenna has secondary lobe, ground interference signal can enter reception system by secondary lobe.A piece reception antenna can be specially set in earth station and offset signal generating circuit, the circuit includes wave filter, width phase adjustment circuit, offsets the modules such as remaining detection, the ground interference signal of collection is offseted with receiving branch interference signal, reaches the purpose for suppressing interference.
Description
Technical field
The present invention relates to the estimation from ground interference signal and suppressing method, additional interference are pressed down in satellite communication system
Antenna method processed and interference eliminate combine method, and in particular to a kind of satellite communication system ground interfering signal suppressing method with
Device, belong to wireless communication field.
Background technology
Briefly, what is then carried out in being used satellite as between exactly tellurian radio communication station is logical for satellite communication
Letter.Track is different as residing for repeater satellite, can be divided into synchronous satellite communication and mobile satellite communication.Satellite communication system includes logical
Letter and the armamentarium for ensureing communication, typically by space subsystem, communication earth station, tracking remote measurement and command subsystem and monitoring
Manage four parts such as subsystem composition.The microwave frequency band such as satellite communication generally use C frequency ranges and Ku frequency ranges.The characteristics of satellite communication
Including：Communication distance is remote；Broadcast mode works, and can carry out multiple access communication；Message capacity is big, is applicable multiple business transmission；Can
By property height；Topological ability is strong etc..
The content of the invention
The terrestrial wireless communication station of satellite communication system is communicated with satellite, to eliminate ground interference signal, using outer
Add ground to disturb reception antenna, and combine corresponding interference cancellation techniques, the present invention proposes a kind of effectively suppression ground interference
Communication technology of satellite.
Technical scheme is as follows：
Satellite communication system mainly includes ground communication station and telecommunication satellite, it is characterised in that utilizes artificial earth satellite
Radio wave is forwarded as relay station, so as to realize the communication between two or more ground communication stations；
When sending information：Transmission signal delivers to antenna through circulator, sends microwave signal orientation by large-scale antenna, delivers to
The telecommunication satellite of planned orbit, relay transmission is carried out to signal by satellite, delivers to other ground communication websites.
During receive information：The information sent by other earth stations, via CSR communications satellite relay, deliver to ground communication station and connect
Receive, reception signal enters from antenna, enters receiving channel by circulator.Satellite communication earth station antenna is all at a certain angle
Sky is placed, antenna is generally huge, has good directional properties, to reduce the influence of ground interference signal to greatest extent.
But because antenna has secondary lobe, ground interference signal can enter reception system by secondary lobe.This interference signal can be used additional
The method of ground interference reception antenna is eliminated.
Described satellite communication system disturbance restraining method, it is mainly used in suppressing ground satellite in satellite communication system and communicates
Ground interference signal received by standing, the signal mainly enter reception system by reception antenna secondary lobe.
Described satellite communication system disturbance restraining method, reception antenna is disturbed to extract ground interference letter by additional ground
Number, and this signal is sent into and offsets signal generation unit, generation it is similar to the ground interference signal in receiving channel offset letter
Number, complete to offset in receiving channel, to eliminate ground interference signal.
Described satellite communication system disturbance restraining method, feedback circuit is established in receiving branch, when offset signal with
When ground interference signal in receiving branch offsets incomplete, remaining received branch road extraction is offseted, can adaptively adjust and offset
Signal generation unit, improve and offset the output of signal, satisfied effect is offseted until drawing.
The invention provides a kind of satellite communication system disturbance restraining method, it is characterised in that is disturbed by additional ground
Reception antenna extracts ground interference signal, and offsets signal needed for signal generation unit generation through offseting, and in receiving branch
Ground interference signal offseted, with eliminate ground interference.The system mainly includes circulator, dual-mode antenna, ground interference
Reception antenna, offset signal generation unit, adder etc..
Wherein,
Described circulator, transmit signal unidirectional loop, for isolating transmitting and reception signal；
Described dual-mode antenna is ground communication station transmitting with receiving common antenna；
Reception antenna is disturbed on the ground, for receiving ground interference signal；
It is described to offset signal generation unit, including wave filter, width phase adjustment circuit, the modules such as remaining detection are offseted, use
In produce it is similar to receiving branch ground interference signal offset signal, and complete to offset and remaining detect, offset signal adaptive
The functions such as adjustment；
Described adder, for completing to offset offseting for signal and receiving branch ground interference signal.
Advantages of the present invention：Because satellite communication system ground communication station dual-mode antenna has secondary lobe, ground interference will not
It is evitable that its receiving channel is entered by secondary lobe, so as to influence the reception to normal signal.The method of the invention, utilization are additional
Ground interference reception antenna extraction ground interference signal, by offset signal generation unit generation can adaptively adjust offset letter
Number, and offseted with receiving branch ground interference signal, it can preferably suppress the influence of ground interference.
